Summary:
- kinetic-molecular theory is a theory that explains the states of matter and is based on the idea that matter is composed of tiny particles that are always in motion.
- The theory is most easily understood as it applies to gases and it is with gases that we will begin our detailed study.
- An ideal gas is an imaginary gas whose behavior perfectly fits all the assumptions of the kinetic-Molecular Theory.
- In reality, gases are not ideal, but are very close to being so under most everyday conditions.
